Abstract
The utility model discloses a dense archives rack bottom girder which comprises a main girder, a plurality of cross beams, a main sprocket wheel, a plurality of large sprocket wheels, a plurality of small sprocket wheels, a main shaft, a plurality of auxiliary shafts, a plurality of chains and a plurality of traveling wheels, wherein the main sprocket wheel is connected with the outer end of the main shaft; the cross beams are welded on the main girder; the four cross beams are symmetrically arranged at the left side and the right side of the main girder; two groups of auxiliary shafts are arranged between the cross beams and symmetrically arranged at the left side and the right side of the main shaft; the plurality of traveling wheels and the large sprocket wheels are arranged on the auxiliary shafts in parallel; and the large sprocket wheels are respectively linked with the corresponding small sprocket wheels arranged on the main shaft in parallel. In the utility model, a spherical-outside-surface ball bearing with seat is respectively arranged under the cross beam, and on the main shaft and the auxiliary shafts. Due to the arrangement of the spherical-outside-surface ball bearing with seat on the main shaft and the auxiliary shafts, the coaxiality and the concentricity of the dense archives rack bottom girder can be guaranteed, the rack body can be led to move and walk in a more flexible, portable and stable way, and the dense archives rack bottom girder has simple structure, convenience and practicality, and low cost.
Description
Technical field
The utility model relates to a kind of intensive frame member, relates in particular to a kind of concentrated archive shelf bottom girder.
Background technology
Existing concentrated archive shelf bottom girder is that 0.9 meter every section splicing is formed, and in utilization and operation, is easy to become flexible, rocks, is out of shape.
Summary of the invention
The purpose of this utility model is: overcome the above-mentioned defective of prior art, provide a kind of walking more flexible, light, concentrated archive shelf bottom girder stably.
The purpose of this utility model realizes by following scheme: be made up of girder, a plurality of crossbeam, head sprocket, a plurality of hinge wheel, a plurality of minor sprocket, main shaft, a plurality of countershaft, a plurality of chain, a plurality of travelling wheel; The main shaft outer end connects head sprocket, crossbeam is welded on the girder, crossbeam has four and is symmetricly set in the girder left and right sides, be provided with two groups of countershafts between crossbeam, be symmetricly set in the main shaft both sides, be set up in parallel travelling wheel and hinge wheel on the countershaft, hinge wheel all by chain respectively be set up in parallel on main shaft corresponding minor sprocket and connect.
Below the crossbeam described in the utility model, be equipped with the roller bearing units of usheing to seat on main shaft and the countershaft roller bearing units of usheing to seat be installed.
Head sprocket 18 teeth described in the utility model, hinge wheel 24 teeth, minor sprocket 12 teeth.
Girder flanging described in the utility model, rectangle is welded into a whole.
The utility model can be guaranteed its axiality, concentricity owing to main shaft, countershaft are equipped with the roller bearing units of usheing to seat, and it is more flexible, light, steady that support body is movably walking, and simple in structure, convenient and practical, with low cost.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is Figure 1A-A view;
Fig. 3 is Fig. 2 B-B view.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is elaborated.
Present embodiment is made up of girder 1, crossbeam 2, head sprocket 3, hinge wheel 4, minor sprocket 5, main shaft 6, countershaft 7, chain 8, travelling wheel 9, the roller bearing units 10 of usheing to seat.Main shaft 6 outer ends connect head sprocket 3, girder 1 flanging, rectangle is welded into a whole, crossbeam 2 is welded on the girder 1, and crossbeam 2 has four and be symmetricly set in girder 1 left and right sides, is equipped with the roller bearing units of usheing to seat on main shafts, the countershaft below the crossbeam 2 roller bearing units 10 of usheing to seat is installed.2 on crossbeam is provided with two groups of countershafts 7, and is symmetricly set in main shaft 6 both sides, is set up in parallel travelling wheel 9 and hinge wheel 4 on the countershaft 7, hinge wheel 4 all by chain 8 respectively be set up in parallel on main shaft 6 corresponding minor sprocket and connect.Present embodiment head sprocket 18 teeth, hinge wheel 24 teeth, minor sprocket 12 teeth.
Operation principle of the present utility model is: when being installed in intensive the crank rotation on the side plate and shaking, driving head sprocket by transmission device rotates, head sprocket drives the minor sprocket that is fixed on the main shaft by main shaft, and minor sprocket drives hinge wheel, countershaft and travelling wheel by chain and rotates.Because main shaft, countershaft are equipped with the roller bearing units of usheing to seat, and can guarantee its axiality, concentricity, it is more flexible, light, steady that support body is movably walking.
